yMy invention herein described is adapted fp-ry use with my invention described in my 'applicationfor aU. S. Letters-Patent, Se-

:,i'ial-.No.` 647,345, filed September 2, 1911,

' 'andofwhichathis .application is a division. .,As illustrated in the drawing, my improved instantaneous water heater is made 4ofthe ordinaryrshape andin the ordinary lssizea and is,.composed of the usual metal casing. '1, .which is `supported by means of legs erstandards Qat the bottom of the samer/such legsbeng-adapted to rest on the iopr.to'hold..the heater in a vertical posi- .tionuand .being securedto the casinglp.. in

any suitable manner. Vithin the casing 2 1s an inner jacket 3 which is secured at the upper end of the same to a supporting plate Ll, and at its lower end is secured to a like plate 5 and to the flanged portion G of the metal casing 1. At the upper endr of the casing 1 is a cover 7 and said cover has a hollow interior 8 which isadapted to communicate with the fluid chamber 9, which is formed between the inner jacket 3 and an outer jacket l0, said last named jacket beine secured at its upper end to the plate et and at its lowerend to the plate 5.

l 1Within the Huid chamber 9, which extends entirely around the combustion chamber 11 formed by the inner jacket 3, and spaced equally around the same, is a series of flue tubes or pipes l2, and said tubes are adapted to extend between the' plates 4 and 5, and are secured thereto by means of the tube fastening device 13.

In the center of the combustion chamber 11 and supported therein by means of the bracket 19 is a rod 20, and such rod i's made of a non-expanding metal and extends upward through an opening Q1 in the cover 7, through which it is slidably mounted, while a cover 9,2 of insulating material is placed around said rod to protect it from the heat from said combustion chamber. The top of the rod 2O is tapered to a point for the purpose to be hereinafter described.

A burner 23 is provided at the bottom of the combustion chamber 11, and such burner is circular in shape and formed integral with the bottom 24, and has openings 25 in the upper face of the same, and such openings are adapted to communicate with the hollow interior 26 of said burner. Into each of the openings 9.5 in the burner 23 a burner tip or nipple 27 is adapted to be placed, and the upper end of the same extends to a height coincident with the plate 5. The burner 28 and bottom 24C are adapted to be swung downward when desired, and this is accomplished by means of a swivel: joint 28 at one side of the same, andthe other side of said burner. and bottom is secured in itsv upright position by means of a check or latch Q9.

The outer jacket 10 is adapted to form a passageway 30 between the same and the casing l, and saidpassageway extends entirely around within said casing and commlinicates with-the tubes 12h51 a passage? point substantially near the opening way 81 below the same and formed by the flanged portion 6 of the metal casing 1 and the lower end of the yinner jacket-3 so that the products of eoinlmstion may pass from 1. the Combustion'Chamber 11 and ,lownward through the tubes 12, thence through the passageway 31 and upward through the passagewayV 30, at the upper end of which is a lue connection 3Q for carrying away such waste products of combustion.

At the top of the cover T and at a point near theeenter of the same is a. diseharge pipe 34 for drawing' huid trom the fluid ehamber 9 and through the hollow interior 8 of said cover. The top of the Cover 7 is also provided witha post 35, which is at a 21 in said cover, and said post has a fulcrum 3G thereon for the purpose of pivoting an arm 3T thereon, while said arm also extends over the pointed upper end of the rod 2O and beyond the same, and engages by its free en d 3S with an arm 3D which is pivoted in a ifi'ilcrum 40 on the top of the cover 7. A

' set screw 38 is fixed in the end of the arm and is adapted to bear by the screw end of the same with the free end 38 of the arm 3T for the purpose ol regulating the distant-e between said arms, thereby regulating the temperature ot the water. The arm 39 extends beyond the outer casing 1 of the heater and connects with a valve, as hereinafter described.

Above the casing 1 is a fluid valve easing 41 'which is adapted to be connected to the water supply pipe 41 by its supply opening 42, and said easing has an inverted plunger 43 within the saine, said plunger operating between the walls 4l ot' said casing, while the side walls of said plunger are provided with ports 4G therein and havea packl in" rine 4T below sur-h )orts for )reventinfr D l'* b the binding` of the metal of said walls 44 and the walls 45 of said plunger. The bottom ot' the plunger 43 is covered with a sheet ot wireI gauze 43 to prevent any dirt ,or foreign substance 'from passing,r throughthe valve easing 41 and into the heater. The easing l1 is also provided with an enlarged chamber 4S above-the plunger 43, and eomweting with lsaid chamber a passageway 49, whieh connects with the outlet port 50.

At'the bottoni ot' the plunger 43 and at the-renter of the salue is a rod 51 whieh extends downward, and has4 a lug 51 on the end thereof and adapted to lit within a link 51a which is connected to the rod 51" and such rod extends through `the valvecasing Ll-l and through the ordinary .stalling box 59. and enters a iuel valve easingr 53 lthrough another stalling' box 54 atthe top ot" the same. ',lhe valve easing 53 is provided with an outlet port 55 through which the fuel is adapted to enter the leater by means of the supply pipe 56 secured therein, and a valve 5 is secured to the end of the red 5 1b extending downward from the valve casing 41 and is adapted to open and close the port 58 within the inner wall 63 of the casing 53 by the operation of the fluid valve 41 above the same. The outlet port 55 communicates with a chamber 59 in which the valve 57 is adapted to operate and a spiral spring 60 is placed around the rod 5l and its movement is limited by the upper part of the casing and the valve 57. At the other side of the valve easing 53 is an inlet port G1 and such port communicates with a chamber 62 which is below and separated from the chamber 59 by the inner wall 63, while a rod 64 enters said chamber from below and through' the valve easing 53 and a stuft'- ing box 65, andis secured at its lower end to the arm 39, while the upper end of the same carries a valve 6G which is adapted to control the opening or; port 58, as hereinafter explained. Around the rod 64 and within the valve casing 53 is a spiral spring G7, which is adapted to rest between the lower wall of said casing and the valvei57 to hold said valve in its raised position.

The fluid supply pipe 41 after -connecting to the outlet port 50 of the valve casing 41 passes downward along` the side of the casing 1 of the heater and connects with the fluid chamber 9 in order to supply the same with water or other fluid to be heated, while the fiuid supply pipe 56 after leaving the valve casing 53 passes downward along the side of the casing 1 in a manner similar to the fluid supply pipe 41 and connects with the swivel joint 28 so that the fuelpassing through the supply pipe 56 may enter the hollow interior 26 of the burner 23, and the fluid connection will thus remain intact when said burner is swung downward on said swivel joint. Connecting with the fuel supply pipe 5G and at a point previous to the position of the valve casing 53 is a pilot supply pipe 68 which communicates with said fuel supply pipe and is of a much smaller diameter than the same.

The operation of my improved instantaneous water heater is as follows :--\Vhen the water is drawn from the heater through the pipe 34- the pressure of the waterf supply in the pipe 41 bea rs against the plunger 43 in the valve casino; 41 and raises the same, so that the water p; ...ses through the ports 16 and into the chamber 4S and downward through the passageway 49 and the port 50 and throughV the pipe 41 to the-fluid chamber 9 ot the heater. f s the plunger 43 in the valve easing 4l. rises by the pressure of thewateuthe rod 51`eonneeting with the bottom ot the same will be likewise raised, so that the valve 5T secured to the lower end of the rod 51 will thus be raised by the corr nection of said rods by the link 51l1 to open the port 58 below the same and thus allow for the passage of the fuel through such port, since the normal position of the valve 6G on the rod 6l is away from the port 58, as hereinafter explained. When the valve' 57 Ais thus raised from the port 58 in the inner wall 63 of the valve casing 53, the fuel entering through the port 6l from the fuel supply pipe 56, passes into the chamber 62, and thence through the port 58 and into the chamber 59 and out through the port 55 and downward through the pipe 56 and enters the hollow interior 26 of the burner 23 through the swivel joint 28 connecting said pipe and burner. The fuel then passes upward through the openings and the burner tips or nipples 27 and is ignited upon issuing from the top of the same by means of the pilot light which is kept burning constantly. The products of combustion of the fuel pass into the combustion chamber ll and thence downward through the tubes 12 within the fluid chamber 9, and 'then through the passageway 3l and into the chamber 30, and is then exhausted into the chimney or flue through the flue connection communicating with the top of said chamber. The products of combustion when at the top of the combustion chamber are in aheated condition and when passing downward through the tubes 12 will become gradf Aually cooled by its contact vwith the inside of such tubes, the outsides lof which are surrounded with the water, and as the hot water rises on account of its being lighter than the cold water, which is admitted at the bottom of the heater, the products of combustion will become cooler as they near the bottom of said tubes. This will aid the circulating of said products of com-bustion as the cooler gases will tend to raise the same upward in the chamber 30 and to the flue connection 32. As the water is drawn from the heater through the pipe 34.- and the fuel entering the combustion chamber 1l and being ignited by the pilot light therein. heats the -water which is in the'luid chamber 9, and suchv heated water being of a lesser specific gravity than the unheated water entering the lsaid liuid chamber Aby means of the supply pipe 41,it will rise and pass into the hollow interior 8 of the cover 7, and thus pass through the opening 33 and into the pipe 34 above the same, when the water is' being drawn. The rising of the warm water is also assisted by the pressure of incoming water. The heat from the combustion of the fuel in the combustion chamber and through the tubes 12 and chamber in said combustion chamber, such rod will not be affected by the heat from said chamber but will retain its ordinary length at all times. When the heater has become'heated to a certain degree of temperature as lixed by experiment and as set by the adjusting screw 38 in the arm 39, the heater on eX- panding will raise the post 35 and will thus allow lthe free end 38 of the arm 37 to drop, whereupon Athe arm 39 will be released and the .spring 67 will raise the rod 6i and the valve /66, so that such valve will close the `port 58, and thus shut off the flow of fuel through the valve casing 53 and the pipe 56 andginto the burner 23. The casing 1 on expanding will slowly close the port 58, as

described, so that when the fluid being f drawn from the heateris gradually getting warmer the valve 66 will be slowly rising and reducing the flow of fuel through said port. In this manner the heater will have 'a perfect regulation so that as the iuid becomes warmer the supply of fuel for combustion becomes smaller, while as the water or other fluid becomes cooler the casing 1 will contract and thus open the port ,58 by means of the fulcrum 36, which will tilt the arm 37, thereby raising the free end 38 thereof and drawing down the free end 39 of the arm 39, which will place tension on the Aspring 67 in the valve casing 53, 4and thus draw the rod 64 and valve 66 downward to open said port. The post 35 on the cover 7 acts as a fulcrurn for the arm 37 and the fulcrum 40 carrying the arm 39, will act as a multiplier for the regulation at the free end 39 of the arm 39, in .that the heater contracts both the post 35 and fulerum 40 will drop downward on account of both being fixed to the same cover 7, as the rod 20 is of a non expanding metal and retains its original height the free end 39 ofthe arm 39 will be lowered just about twice the distance it would if a single arm and fulcrum were used.

It will readily be seen that with my improved form of instantaneous water heater the arrangement of the parts and system of the same is such that both the cool ,water and cool gases are in the bottom of said heater While the heated products of combustion and heated water are at the top of the same. The advantage derived from this is that the natural tendency of both heated water and gases is to rise,.and the operation of the heater will be more efficient thereby.

What I claimas my invention and desire to secure by Letters-Patent is- The combination with a water heater having a water valve and thermostatic means, of a valve casing having a single partition within the same, a port in said partition, a seat on each side of said port, a valve on one side of said partition, said valve nor- 130 mally engaging one sf said seats and being -adapted to `he automatically opened and port when said temperature becomes excessive.

l In testimony whereof, I the said JOHN P. REINEOKE have hereunto set my hand.
